GRAND RAPIDS, MI — Locally heavy rainfall, thunderstorms and even funnel clouds are possible Wednesday as a storm system barrels toward West Michigan.

The National Weather Service in Grand Rapids issued a special weather statement saying conditions are ripe for "sudden" and "rapid" formation of funnel clouds in the region.

Forecasters were tracking a line of storms developing on and south of a Muskegon-to-Mount Pleasant line, moving north around 25 mph.

"While no funnel clouds or tornadoes have been reported at this time, the meteorological conditions today support the rapid and sudden development of funnel clouds and even brief, weak tornadoes," forecasters said in the special statement.
